Next month, we're about to embark on a month long expedition to the remote island of South Georgia, as part of a coastal habitat mapping research project. I've been using your app to great effect in the Falkland Islands and really like the Terrain Awareness function, based on SRTM data.
South Georgia has some serious terrain, and I am trying to plan the missions before we depart, while connected to the internet, to download basemaps and the terrain information. However, we are going to be based off a boat (potentially with zero internet access), and there may be the situation that we want to complete some opportunistic mapping missions which I haven't been able to pre-plan. Is it possible to batch download a series of base map tiles and terrain information for a large area.
I guess one option may be to plan a very very large missions, thereby covering a large an area as possible, and therefore downloading large sections of basemaps. However, South Georgia is quite large and I'm not sure if this is feasible.
Are there other options, or functionality with the App that I am not familiar with?
